Effect in two models of training for special strength in volleyball: Practice application in two stages in C.V. Gran Canaria

Abstract

This study was performed to compare the effects of two different modalities of special power training for the improvement on the vertical jumping, in which the players of the Gran Canaria Volleyball Club were trained during the sessions of 93/94 and 95/96. The training groups were: A) (n = 7), session 93/94, trained only with overload, by using, as transformation, just volleyball training. B) (n = 6), session 95/96, add to this method plyometric exercises for the enhancement weight training. The test items used to prove the results were based on Bosco: Squat Jump (SJ), Countermovement (CMJ), Squat Jump with load (SJbw), Abalakov with block technique (Block) and Drop Jump (DJ) from different heights. On the one hand, gains in height of vertical jump were observed after a method of training that includes plyometric excercise at medium and medium-high intensity and by each different depth jumps (DJ), specially in those ones selected for the transformation of weight training. On the other, when any plyometric method was used there was no enhancement, but a loss of height in vertical jumping.
